With healthcare shifting to the outpatient setting, this study examined whether outpatient clinics operating in business occupancy settings were conducting procedures in rooms with ventilation rates above, at, or below thresholds defined in the American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers/American Society for Health Care Engineering Standard 170 for Ventilation in Health Care Facilities and whether lower ventilation rates and building characteristics increase the risk of disease transmission.

Ventilation rates were measured in 105 outpatient clinic rooms categorized by services rendered. Building characteristics were evaluated as determinants of ventilation rates, and risk of disease transmission was estimated using the Gammaitoni-Nucci model.

When compared to Standard 170, 10% of clinic rooms assessed did not meet the minimum requirement for general exam rooms, 39% did not meet the requirement for treatment rooms, 83% did not meet the requirement for aerosol-generating procedures, and 88% did not meet the requirement for procedure rooms or minor surgical procedures.

Lower than standard air changes per hour were observed and could lead to an increased risk of spread of diseases when conducting advanced procedures and evaluating persons of interest for emerging infectious diseases. These findings are pertinent during the SARS-CoV-2 pandemic, as working guidelines are established for the healthcare community.

The protection against aerosol transmission provided by masks vs face shields or in combination when speaking indoors is not well understood.

To simulate a human source, an aerosol generating system was made using a bacterial suspension in a nebulizer attached to an oxygen cylinder. A fan connected to the nebulizer created aerosols. Transmitted aerosols were detected using blood agar plates at 0.1524 and 1.8288 meters from source, simulating exposed person. The study was performed under controlled conditions at room temperature in a biohazard hood with high-efficiency particulate air (HEPA) filter and UV light.

When face shields were used alone, significant numbers of bacterial colonies grew on blood agar plates. When a mask used alone for both the subjects (source and exposed), the blood agar yielded minimal colony forming units at both distances. When face shields were used in combination with masks, no significant improvement was observed as compared to masks alone.

Our results were similar to what have been observed in related studies.

Surgical masks alone provided good protection, surpassing the protection provided by face shields alone. Both used together provided the best protection, although the combined protection was similar to surgical masks use alone.

Candida auris was first described in Japan in 2009 and has since been detected in over 40 countries. The yeast is concerning for multiple reasons, primarily (1) challenges with accurate identification; (2) reported multidrug resistance; (3) published mortality rates of 30%-60%; and (4) persistence in the environment associated with human transmission. We report the emergence of a healthcare-associated cluster in the Greater Vancouver area in 2018 and describe the measures implemented to contain its transmission.

Cases were identified through passive and ring surveillance of affected wards. Positive isolates were sent to provincial and national reference laboratories for confirmation and genomic characterization. Extensive infection control measures were implemented immediately after the initial case was identified.

Four cases were identified during the outbreak. In a 4-month period, over 700 swabs were collected in order to screen 180 contacts. Whole genome sequencing concluded that all isolates clustered together and belonged to the South Asian clade. No isolates harbored FKS gene mutations associated with resistance to echinocandins. Infection control measures, including surveillance, education, cleaning and/or disinfection, patient cohorting, isolation, and hand hygiene, effectively contained the outbreak; it was declared over within 2 months.

The spread of C auris in healthcare facilities has not spared Canadian institutions. Our experience demonstrates that strict infection control measures combined with microbiological screening can effectively halt transmission in healthcare centers. The necessity of active prospective screening remains unclear.

While self-reported confidence in endoscope reprocessing was high (9 out of 10), knowledge of best practices in this regard lagged (average assessment score of 62%).

This systematic review had 2 aims. First to identify the incidence of urinary tract infection (UTI) and bacteriuria in people undertaking intermittent catheterization (IC), second to determine the effectiveness of antiseptic cleaning of the meatal area prior to IC in reducing the incidence of UTI and bacteriuria.

A systematic review was conducted. Medline and the Cumulative Index to Nursing and Allied Health Literature electronic databases were systematically searched between January 1, 1990 and January 31, 2020, to identify studies that reported either the incidence of UTI or bacteriuria or the impact of using antiseptics for meatal cleaning prior to IC on incidence of these same outcomes.

Twenty-five articles were identified for the first aim, 2 articles for the second. The proportion of participants experiencing ≥1 UTIs per year ranged from 15.4% to 86.6%. Synthesis of these studies suggest a combined incidence of 44.2% (95%CI 40.2%-48.5%) of participants having ≥1 UTIs per year. One of the 2 studies exploring the benefit of antiseptics in reducing UTI suggest some potential benefit of using chlorhexidine in reducing UTIs. Both studies have significant limitations, making interpretation difficult.

A large proportion of people undertaking IC in the community have UTIs each year. Evidence on the role of antiseptics in the prevention of UTI for people who undertake IC remains unclear.

Endobronchial ultrasound (EBUS) guided intranodal forceps biopsy (IFB) is considered complimentary to EBUS-TBNA for patients with intrathoracic lymphadenopathy when either additional tissue is requested for comprehensive molecular testing, or for suspected lymphoma and sarcoidosis. This is a systematic review and meta-analysis to investigate the diagnostic yield and complications of combined EBUS-IFB and EBUS-TBNA compared to EBUS-TBNA alone.

We performed a systematic search of MEDLINE, Embase, and Google Scholar for studies evaluating the use of EBUS-IFB for diagnosis of intrathoracic adenopathy, assessing the quality of each study using the QUADAS-2 tool. Using inverse-variance weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed the complications related to the procedure.

Six observational studies with 443 patients undergoing 467 biopsies were included in the final analysis. Meta-analysis yielded a pooled overall diagnostic yield of 67% (312/467) for EBUS-TBNA andr surgical biopsies.

A life-threatening complication of coronavirus disease 2019 (COVID-19) is acute respiratory distress syndrome (ARDS) refractory to conventional management. Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is used to support ARDS patients failing conventional management. Scoring systems to predict mortality in VV-ECMO remain unvalidated in COVID-19 ARDS. We describe the largest COVID-19 VV-ECMO single-center experience to date and assess the utility of standard risk calculators.

A retrospective review of a prospective database of all COVID-19 VV-ECMO patients, cannulated between March 15

and June 27

, 2020, at a single academic center was performed. Demographic, clinical, and ECMO characteristics were collected. The primary outcome was in hospital mortality; survivor and non-survivor cohorts were compared utilizing univariate and bivariate analyses.

Forty COVID-19 ECMO patients were identified. Of the 33 patients (82.5%) off ECMO at time of analysis, 18 patients (54.5%) survived to hospital dtion for ECMO.The exposure of Bacteroides fragilis to highly oxygenated tissues induces an oxidative stress due to a shift from the reduced condition of the gastrointestinal tract to an aerobic environment of host tissues. The potent and effective responses to reactive oxygen species (ROS) make the B. fragilis tolerant to atmospheric oxygen for several days. The response to oxidative stress in B. fragilis is a complicated event that is induced and regulated by different agents. In this review, we will focus on the B. fragilis response to oxidative stress and present an overview of the regulators of responses to oxidative stress in this bacterium.Doublecortin-like kinase 1 (DCLK1) is a Doublecortin family kinase involved in a range of brain development processes including cell migration, axon/dendrite growth, and synapse development. read more The Dclk1 gene potentially generates multiple splicing isoforms, but the detailed expression patterns in the brain as well as in vivo functions of each isoform are still incompletely understood. Here we assessed expression patterns of DCLK1 isoforms using multiple platforms including in silico, in situ, and in vitro datasets in the developing mouse brain, and show quantitative evidence that among the four DCLK1 isoforms, DCLK1-L and DCL are mainly expressed in the embryonic cortex whereas DCLK1-L and CPG16 become dominant compared to DCL and CARP in the postnatal cortex. We also provide compelling evidence that DCLK1 isoforms are distributed in the partially distinct brain regions in the embryonic and the postnatal stages. We further show that overexpression of DCLK1-L, but not the other isoforms, in neural progenitors causes severe migration defects in the cortex, and that the migration defects are dependent on the kinase activity of DCLK1-L. Our data thus uncover partially segregated localization of DCLK1 isoforms in the developing mouse brain and suggest different roles for distinct DCLK1 isoforms in the brain development and function.
